At least 12 people were injured due to a blast during the air conditioner repair in the basement of the Supreme Court of Pakistan’s building on Tuesday, sources said.

Speaking to the media outside the Supreme Court, the Inspector-General (IG) of the Islamabad Police stated that three of the injured were transferred to PIMS Hospital, while nine were taken to the Polyclinic.

Two of the victims are reported to be in critical condition.

According to the IG, gas leakage had been occurring in the canteen for several days, and the explosion took place during maintenance work on the air conditioner.

He added that most of the injured were AC technicians, one of whom suffered burns on nearly 80 per cent of his body.

Immediately after the blast, court authorities ordered the evacuation of all individuals inside the building.

Police and security agencies are currently assessing the impact of the explosion.

Immediately after the blast, the area surrounding the Supreme Court was sealed, and both court staff and visitors were shifted to safe locations.
